WARP-PRINTING MACHINE. i

SPEGIFIGATIONforming part of Letters Patent N0.'750,514, dated January26, 1904. Application filed March 4, 1902. Serial No. 96,642. (Nomodel.)

To all whom it may concern:

Be it known that we, GEORGE H. WINSLOW and CHABLEs W. DENNETT, of NorthAdams, in the county of Berkshire, State of Massachusetts, have inventedcertain new and useful Improvements in Warp-Printing Machines, of whichthe following is a complete specification, reference being had to theaccompanying drawings.

The object of our invention is to produce an improved machine forprinting color designs upon warps preparatory to weaving the threads ofsuch warps into figured fabrics in which the figure referred to is inwhole or in part derived from the printing of the warp.

The machine shown and described in this application is one adapted tocarry out the process described in our concurrent application, SerialNo. 96,641, filed the 4th day of March, 1902, to which applicationreference is herein made for complete description of the process andmode of operation of the machine.

In the accompanying drawings, Figure I is a side elevation of completeapparatus for carrying out our process, the illustration being mainlydiagrammatic in character. Fig. II is a similar top plan view of thesubjectmatter of Fig. I. Fig. III is a top plan view illustrating thecondensing-reed and showing the same at right angles to its frame. Fig.1V is a view similar to Fig. III, illustrating the reed set obliquely toits frame for the purpose of condensing a warp. Fig. V is a sideelevation of the subject-matter of Fig. III. Fig. V1 is a side elevationof the reed and its supporting members detached from their frame. Fig.VII is an enlarged view ofa portion of the subject-matter of Fig. I,illustrating details of the printing-roller-driving mechanism. Fig.VIII, is aview of a portion of the subject-matter of Fig. VII, taken atright angles thereto.

Referring to the numerals on the drawings, 1 indicates each of anordinary series of beams, of which four are illustrated and which arerevolubly mounted, as in a suitable frame 2.

' Upon the beams 1 are wound warp-threads 3,

from which they are led, as through an ordinary base-reed L and througha condensing:

reed 5 over rollers 6 of a sizing-machine 7 of any ordinary or suitabledescription. Such mechanism being clearly understood in the art, it issufficient here to specify that the warp 8, which receives form inpassing through the reed 5, is carried into the sizing-vat by passingunder a depressed roller 9, whence passing through two pairs ofsuitably-driven rollers 10 and 11 it has a portion of the sizing liquidsqueezed out of it. From the second pair of rollers 11 the warp8 isconducted over a moisture-regulating drum 12, which is revolubly mountedin suitable bearings in a pendent frame 13. The drum or cylinder 12 isheated, as by the internal application of steam. Means for regulatingthe heat as well as the size of the drum and the extent of the area ofcontact between it and the warp 8 afford means of nicely regulating thedegree of moisture in the warp 8.

1 indicates a guide-roller, by means of which the warp is properly bentover the drum 12 and directed at a proper angle over a presserroller 15,which is adjustably suspended from the frame 13. The roller 15 isadapted to bear against a printing-roller 16, suitably mounted in aframe 17, which carries the ordinary color-boxes, feed-rollers, andother appurtenances with which printing mechanism of this character isusually provided. The printingroller is mechanically driven in a waywhich will be hereinafter specified; but the presserroller 15 derivesits motion from peripheral contact with'the printing-roller 16. The warp8 in passing between the rollers 15 and 16 receives the imprint of thedesign from the printing-roller. It is unnecessary to further specifythe details of the printing mechanism, since it may be of any suitableconstruction well known in the art. In passing between the rollers 15and 16 the warp is provided with a backing-cloth, which should move atanequal rate of speed with the warp in order to prevent disturbance ofthe threads thereof until after the print is dry, and we thereforeprovide in our apparatus mechanism for accomplishing that result. Thebacking-cloth 18 is carried in a roll 19, journaled as between uprightframe-pieces 20.

' work required of the apparatus.

21 indicates a guide-roller, over which the backing-cloth 18 is directedto a second guideroller 22. Additional guide-rollers 23 and 24 serve topresent the backing-cloth 18 at a proper angle to the roller 15, inpassing over which the warp is laid upon the backing-cloth. In passingbetween the rollers and 16 the backing-cloth 18, with the warp 8 uponit, (indicated by the numerals 8 18,) passes to a large drying-cylinder25, journaled, as indicated at 26, in the frame 13.

28 indicates a guide-roller, which is preferably located for economy ofdimensions near the cylinder 25 at such a point as will compel contactbetween the warp 8 and cloth l8e throughout the greater portion of theperiphery of the cylinder 25. From the roller 28 the warp and cloth passover a guide-roller 29 and thence to rollers 30 and 31, respectively.The peripheries of the rollers 30 and 31 are properly substantiallytangential to a common plane, so that the warp 8 and cloth 18 proceedtogether to the roller 30, where they separate, the cloth 18 going overa pair of tension-rollers 32 and 33 to a take-up roll 34. The rollers 32and 33 and the roll 34 are driven at a proper rate of speed to keep thecloth l8 taut and moving at a rate uniform with that at which the warp 8moves.

In the apparatus illustrated it is important to provide means that willinsure sufficient dryness in the warp 8 when it leaves the backing cloth18, which will prevent unequal stretching or shrinkage of thewarp-thread or running of the color of the print. For that reason thedimensions and heating capacity of the cylinder 25 and the extent ofcontact between the periphery of that cylinder and the warp andbacking-cloth must be carefully considered and calculated to thecharacter of the Such details of the construction and manipulation mustnecessarily be left to the judgment of the constructor and operator andcan only be pointed out generally, as hereinbefore set forth, in ageneral description of the character of this specification.

After leaving the roller 31 the warp 8, passing over guide-rollers 35and 36, which enable it to clear the roller 25, isbrought into contactwith a final drying-cylinder 37, from which, as by guide-rollers 38, 39,40, and 41, it is conducted, after passing through a comb 42, overguide-rollers 43 and 44 to a loombeam, upon which it is finally wound,ready for the loom.

It should be observed that the same care to preserve uniformity ofmovement of the warp is essential after it leaves the backing-cloth asat any former stage of the process and that accurate timing of themovements of the driving or drying operations of the apparatus must bepreserved up to and including the driving of the beam 45, upon which thewarp is finally wound.

The driving mechanism of our apparatus has been heretofore alluded to ingeneral terms, and we will now proceed to describe the same more indetail. Referring, accordingly, to

Fig. 'VIII, in view of Figs. I, H, and VII,

as showing a practicable and preferred form of driving mechanism, 47indicates themain driving shaft of the apparatus, to which power may beapplied as required, as through a split pulley 48., It is of courseassumed that where shafts or Wheels are mentioned they are suitablymounted in the usual manner upon some part of the frame of the apparatusor other supports available in thebuilding where the apparatus iserected; but detailed description of journal-bearings and similarimplied members will 'be omitted except where it appears to beespecially required. The shaft 47 carries a fixed pinion 50, whichmeshes with a stud-supported gear 51, that communicates motion to theshaft 52 of the printing-roller 16, as through a pinion 53, fixed to theshaft 52. The roller 15, suspended by its axle 54, derives motion, ashas been specified, through peripheral pressure against the roller 16,actual contact between the rollers 15 and 16 being prevented by theintervention of the warp and backing-cloth. Between the pinion and thepulley 48 there is fixed to the shaft a sprocket-wheel-55, which, as bya sprocket-chain 56, communicates motion to a sprocket-wheel 57 upon atransverse shaft 58, which in turn, as by sprocket-wheels 59 and 60,communicates motion to sprocketchains 61 and 62. The former drives asprocketwheel 63, (see Figs. I and 11,) which is geared, as by asprocket chain 64 and suitable intermeshing wheels, to the shaft 65 of afeed-roller 66. 68 indicates a pinion upon the shaft 65, which, as by achain 69, drives a wheel 7 0 upon a shaft 71, a pinion 72 on whichcommunicates motion through a chain 74 to a sprocket 75 upon the shaft76 of the dryingroller 37. A chain 78 communicates motion from a wheel79 upon the shaft 76 to a wheel 80, that drives a gear 90, meshing witha gear 91 upon the shaft 26 of the drying-cylinder 25. Thesprocket-chain 62, meshing with a wheel 95 upon the shaft 96,communicates motion through a pair of sprocket-Wheels 97 and 98 tochains 99 and 100, respectively. The chain 100 is operatively connectedwith the driving mechanism of the sizing-machine 7, as diagrammaticallyindicated. The chain 99 drives a shaft 101, which in turn, throughsuitable belt-and-pulley connections, drives the rollers 32 and 33 andthe take-up roll 34 at the required uniform rate of speed.

The driving mechanism of the apparatus, as above described, has each ofits several parts so timed as to communicate with every rotating memberadapted to impart motion to the warp and backing-cloth when they areunited andwhen they are separated from each other at a uniform rate ofspeed, so that there is nowhere exerted upon either the warp or thebacking-cloth either an acceleration, weight, or drag which tends in theleast to disturb the relations of the threads in the which, working inlongitudinal slots provided for them, respectively, in the bar 108, areprovided underneath the bar, respectively, with wing-nuts 110, by whichwhen the position of the frame 105 is adjusted with respect to the barthrough manipulation of the screw 106 the frame may be securely fixed inplace. The bar 108 is provided near its opposite extremities withswivel-eyelets 111, through which pass the respective side bars 112 of asupporting-frame. The side bars 112 being parallel and the eyelets 111being free to turn, it is obvious that the reed in its frame 105 may be,within certain limits, brought to any required angle, as will appearupon comparison of Figs. III and IV. Each of the eyelets is secured tothe supporting-bar 108, as by a stud-bolt 118, which carries upon itsthreaded extremity a wing-nut 11 1. By this means whenever the positionof the reed is fixed it may be secured in that position by turning thenut 1141 and drawing the eyelets 111 fixedly against the bottom of thebar 108. The operation of the reed 5 as a condenser is accomplished bysetting it in a position oblique to the side bars 112. When the reed isat right angles to the side bars, the extreme lateral threads 115 and116 of a warp are at their extreme limit of separation. If the reed bemoved to an oblique position, the threads 115 and 116 will be drawnsomewhat closer together, and the spaces between all of the intermediatethreads will be correspondingly and distributively lessened. It isobvious, therefore, that within the limits of adjustment of the reed thewidth of a warp passing through its dents may be varied at will andwithout interrupting the operation of the apparatus. By this means thenumber of warp-threads presented to a given surface of the printingrollmay be readily varied for the purpose specified.

The operation of the apparatus as a whole having been described in thespecification of its functions and mechanical structure and theoperation of the condensing-reed having been pointed out more in detail,further description of the operation to one skilled in the art appearsto be unnecessary.

In the foregoing specification and accompanying drawings we have shownand described preferred mechanism for accomplishing a given result; butwe desire to have it understood that we do not limit ourselves to theprecise details of construction of our apparatus, but, as suggested bythe diagrammatical character of the illustration of the machine as awhole, reserve the right to modify and vary the same in all respects, sofar as may be done without departing from the scope of the principle ofour invention.

What we claim is 1. In a warp-printing machine the combination withmeans for imparting to the warp a regulated degree of moisture, printingmechanism, a warp-receiving beam, and a dryingcylinder between said beamand printingmechanism, of means for compelling contact between saidcylinder and the warp and itsbacking-cloth throughout the greaterportion of the periphery of said cylinder, and synchronously-operativedriving mechanism.

2. In a warp-printing machine the combination with suitable drivingmechanism and printing mechanism, of an obliquely-movable reed adaptedto regulate the spaces between the warp-threads passing through itsdents with reference to the printing mechanism.

3. In a warp-printing machine,the combination with a reed, of means foradjusting it obliquely to the warp-threads passing through its dents.

4. The combination with a pair of parallel bars constituting areed-supporting frame, of a reed carried thereby, and means foradjusting the position of the reed obliquely to the bars, at will.

5. The combination with a pair of parallel bars constituting asupporting-frame, of a reed supporting bar obliquely adjustable thereon,and a reed-frame transversely adjustable upon the supporting-bar.

In testimony of all which we have hereunto subscribed our names.
